GAS-MIXER.

SPECIFICATION forming part of Letters Patent No. 595,916, dated December 21, 1897.

Appiiaiion ined December 5, 1895. serai No. 571,187. No modelo To all whom, t may concern.-

Be it known that I, WILLIAM LANesEN- KAMP, J r., a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented new and useful Improvements in Gas-Mixers, of which the following is a specification.

My invention relates to certain new and useful improvements in a device for mixing air with gas,commonly designated gas-mixers, and will be hereinafter more fully set forth.

The object of my invention is to construct a mixer in such a manner that the gas-exit opening thereof cannot by means of any drilling device be enlarged or rebored to increase the area of the gas-jet opening and thereby increase the supply or flow ofthe gas therethrough, and, further, to construct said mixer with a rotatable bead cast in place that will be entirely inclosed in the stem or nipple of the said mixer,said stein being cast or founded in one integral piece with the body of the mixer and with both or one of its ends closed. I attain these objects by means of the mixer illustrated in the accompanying drawings, in which similar numbers of reference designate like parts throughout the several views.

Figure 1 is a longitudinal sectional view of the mixer, taken through the line A B. (See Fig. 2.) Fig. 2 is an end view of the same, looking in the direction of the arrow. (See Fig. l.) Fig. 3 is a broken sectional view of the nipple of the mixer in an unfinished state,

and Fig. 4 is a detail longitudinal sectional view of the intercepting-beads.

The mixer is composed of the exterior atmospheric-air-mixing chamber l, the outer end 2 of which is open to the atmosphere, and the connecting end 3 of the stem or nipple 4, which former is threaded to be connected to a suitable supply-pipe. The opposite end of the exterior chamber is threaded at its interior end to be connected to the burner in the usual or any suitable manner. The nipple 4 is formed integral with and connected to the exterior chamber l by means of the arms 5.

In the chamber 7 of the nipple 4 are inclosed the beads 8, both of which are conical in form and are placed therein with their bases abutting. These beads are drilled longitudinally and centrally and each fit loosely in said chamber and are free to turn or move independently therein. The inletopening 9 is preferably formed in the mold of the mixer or cast therein and the exit or jet opening lO is preferably drilled therein.

The beads 8 are preferably constructed of a good quality of hard tool-steel or other metal capable of being made impervious to any cutting-tool and are'drilled, formed, and finished before being placed in the mold in which the said mixer is to be cast.

The beads 8 are placed in the mold as shown in Figs. 1 and 3-that is, with their bases abutting and their longitudinal axes coinciding with the longitudinal axis of the nipple 4, so that a free and unobstructed longitudinal passage of the fixed area is secured through the nipple 4. The beads are held in their proper positions in the mold by the retainer or anchor ll, as shown in Fig. 3.

It is clear from the foregoing and an inspection of the drawings that if a drill is employed to enlarge the opening of the nipple 4 when the drill has been entered till it contacts with the near bead 8 the same will rotate and cannot be held stationary by any retaining device, which must be applied thereto from the opposite end and which will first contact with the opposite bead, thereby preventing the said retainer contacting the bead against which the drill is in contact and permitting the same to freely rotate with the drill.

I-Iaving thus fully described the nature and construction of this my invention, what I claim as new and useful, and desire to cover by Letters Patent of the United States therefor, is-

l. The combination with a `fluid-supplying device having an orifice for the passage of the fluid, of a chilled drill-obstructer cast in place in said device.

2. The combination with a, ud-supplying device having au orifice for the passage of the Huid, of a chilled drill-obstruoter composed of two frustums of a cone Wit-h their bases together.

3. The Combination with :L Huid-supplying device having an orifice for the passage of the Huid, of :L drill-obstructer composed of two frustums of a, cone with their bases together each of which frustums is supported to indc- 1o pendently rotate.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
